MTR Corporation Limited (.mtr)

The .mtr domain extension is a branded generic top-level domain (gTLD) operated by MTR Corporation Limited, the company behind Hong Kong's Mass Transit Railway system. It is intended for use by MTR Corporation and its affiliates to create a trusted online space for official information, services, and communications related to the railway network. Registration is restricted to the MTR Corporation and its authorized entities, so it is not open to the general public. The domain was delegated in October 2015, following MTR's application during ICANN's new gTLD program. The registry services are managed with technical support from Hong Kong Internet Registration Corporation Limited.
